This is the amount of alcohol by weight. The amount of alcohol by volume (the number you see quoted on cans and bottles) is a little larger. To convert one to the other is also easy. Just divide by the density of alcohol, 0.79 kg/L.

Alcohol by volume: 4.1% / 0.79 = 5.2%.

This does coincide with our hydrometer. We are using a "Triple Scale Wine Hydrometer". In addition to the Specific Gravity, it also shows Balling/Brix, and Potential Alcohol by Volume. Our Starting Potential Alcohol by Volume was 8% and our Terminal reading was 2.8. Difference is 5.2%.

The beer looked a deep golden amber and we're pleased with how it looks. We did do a taste test; we noticed a lot of bitterness from the hops, but we're both fans of that so that's a good thing. There was a great aroma and overall flavor, so naturally we are excited to try it with some bubbles in it.

One last thing we noticed during bottling, was the amount of, what I call, "sludge" at the bottom of the primary. In fact, there was so much, that we could only bottle 47 beers as opposed to our usual 48.
